Resolutions

What is resolution? What is the difference between each of the different resolutions mentioned in this video? What is the presenter's advice for using different resolutions?

    Resolution is the number of pixels on the screen vertically and horizontally. The format of the names are "horizontal number x vertical number" followed by an i or p depending on whether the footage is interlaced or progressive. Interlaced footage renders the odd rows then the even rows from top to bottom, this is the older method that doesn't look very good on the now more common progressive screens. Progressive footage renders just from top to bottom and creates a smoother motion compared to its older predecessor. There are typically two aspect ratios used, 3:4 and 9:16. The names of the different resolutions are the vertical number, such as 480i or 1080p, except for 4k and beyond. Each resolution also has their own name: Standard Definition, High Definition, Full High Definition, 4K Ultra High Definition, and 8k Ultra High Definition. The higher the definition, the more quality and detailed the image is.

    The presenter's advice regarding the use of different resolutions is basically just "don't worry about it" and to not get caught up in getting the latest technology. He says that the most important part is just the video making and that the experience that you gain from making new things greatly outweigh any benefits of getting the new tech.
